Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148672, here are decompositions:
- 3 + 148669 = 148672
- 5 + 148667 = 148672
- 233 + 148439 = 148672
- 269 + 148403 = 148672
- 311 + 148361 = 148672
- 443 + 148229 = 148672
- 479 + 148193 = 148672
- 521 + 148151 = 148672
Showing the first eight; more decompositions exist.
